Key features

Pre-alarm (gentle wake-up)

A low volume gentle alarm starts some time before the main alarm. When you’re in a good sleep phase to wake up, you’ll hear the low volume alarm and wake up refreshed. 30 minutes is usually enough to catch the light sleep phase.

Smart snooze options

Quick snooze

Snooze for a preset time with one click

Custom snooze

Long-click the snooze button to select a specific time

Volume fade in and vibration

The alarm volume gradually increases to gently wake you up. Vibration starts only after the fade-in completes, ensuring a smooth wake-up experience.

Accidental dismiss protection

Long-click to dismiss prevents you from accidentally turning off your alarm when you’re half asleep.

Modern time picker

Features a Jelly Bean-style time picker with a phone-style keyboard. No more spinning through hours and minutes!

Simple Alarm Clock is fully open source under the Apache 2.0 license. Contributions, feature requests, and bug reports are welcome on GitHub.
